7 Claims.

This invention relates generally to printing equipment and moreparticularly to a quoin. Quoins are subject to frequent and hard use andabuse and must operate quickly and easily and it is an object of ourinvention to produce a quoin which is capable and ecient in service.

Briefly described, our invention consists of a channel having an outsideWedge therein together with means for forcing `these members away fromeach other in a straight line, such preventing squabbling of the type,and also exerting the pressure against the type to produce the mostefficient action thereon.

One aim of our invention is to create a quoin which may be manufacturedin any desired length, and we do this by making the elements of thequoin of recurrent configuration whereby they may be cut olf to theproper length without Waste. Another advantage of our invention is themethod of connecting the outside wedge to the webs of the channelmember, such guiding the movement of these respective parts whereby theymust move in the desired direction. Also, the same means prevents thetotal separation of these parts whereby a self-contained unit is had.

Still another advantage lies in the guiding bushing for the key, thisbushing being flush with the outer surfaces of the channel member toform a sturdy and neat appearing structure. Also, the operative end ofthe bushing is readily found as such is circular in shape whereas theother end is of semi-circular shape. Hence, the key must be insertedfrom the correct side, thus insuring clockwise rotation thereof totighten the quoin,

thus giving a uniformity which makes for speed.

Further advantages are due to the positioning of the several elementswhereby inherent advantages relating to strength of the working partsand compactness of structure is had and these will be appreciated as thedescription proceeds.

In the drawing:-

Fig. 1 is a plan view of a chase equipped with two of our improvedquoins.

Fig. 2 is a cross sectional view taken along the line 2 2 of Fig. 5.

Fig. 3 is a View in section taken along the line 3--3 of Fig. 2, theoperating key being shown in dotted lines.

Fig. 4 is taken along the plane of the line 4--4 of Fig. 3.

Fig. 5 is taken along line 5-5 of Fig. 2.

Fig. 6 is a perspective view of the shell member.

Like numerals refer to like parts throughout the several views.

In Fig. 1, 10 indicates the type, 11 the frame therefor, 12 the regletsand 13 our novel quoin.

As is clearly shown in Fig. 5, indicates a Channel member having slots22, see Figs. 1 and 2, and 3o indicates the outside wedge member, suchbeing slidably engaged by the flanges oi' the channel member 20. Thewedge member 3G has staggered parallel surfaces 31 as clearly shown inFig. 2. Pins 32 extend through the outside wedge member and ride in theslots k22, see Figs. 2 and 5, to guide the movement between these twomembers and also to prevent their separation. Thus a self-contained unitis had.

, An inside wedge member 40, having inclined surfaces 41, see Fig. 2, islocated between the outside wedge 30 and the web of the channel member.This inside wedge member is cut away at its center to form teeththereon.

A shell member 75, see Figs. 3 and 6, extends ,25 between the flanges ofthe channel member 2i), the upper end being circular in shape and snuglyfitting a corresponding hole, being brazed therein as indicated at '76,while the lower end, shouldered as indicated at 77, is semi-circular andis likewise received snugly in the other ange of the channel,` thusabsolutely preventing any rotation from occurring. The shoulder 77insures proper positioning of the shell. See Fig. 3.

The operation is apparent. The quoin is inserted in position, forinstance, as shown in Fig.

l, and the circular openings of the shell 'l5 prevents any reversedpositioning o the quoin, and thus the key member 80 will always berotated in a clockwise direction to cause an expansion of the quoin.This sameness of operation makes for speed. Y

Upon rotation of the key 80, the rack teeth 60 and the wedge member 40are moved from the position opposite that shown in Fig. 2 to that 55shown therein and this causes the outside wedge member 30 to engageagainst the adjacent reglet 12 while the channel member abuts againstthe frame 11 and the type 10 are tightly locked in position without anysidewise movement what- 'ibo soever.

The release of the quoin is accomplished in a reversed manner and thepins 32, riding in the slots 22, prevent any separation of the severalparts. Moreover, the parts are substantially en- T closed wherebyprotection thereof is had.

The invention is defined in the appended claims and is to be consideredcomprehensive of all forms coming within their scope.

We claim:

1. A quoin comprising, a channel member, a wedge member tting betweenthe flanges of said channel member, said wedge having wedg ing surfacesthereon, a second wedge member having wedging surfaces engaging thesurfaces 0f the first mentioned wedge member and located between saidrst mentioned wedge member and the channel member, means including a keyfor forcing said rst mentioned wedge member away from the said channelmember and guiding means for said key member, said guiding means beinglocated in but extending unsymmetrically with respect to the oppositeflanges of said channel member for the purpose described.

2. In combination, a channel `shaped member, an outsidewedge memberslidable between the Webs thereof, an inside wedge member having teeththereon, said channel member having a circular opening through one angeand a substantially semi-circular opening through the other iiange and acylindrical shell adapted to be received in said openings, said shellbeing cut away for the purpose described.

3. An article of manufacture consisting of a channel member of identicalcross section along its entire length, an integral outside wedge ofrecurrent cross section slidably engaged between the flanges of saidchannel member, means for preventing lengthwise movement of the wedgewith respect to the channel member, said means including pins extendingthrough said outside Wedge at both sides and being received in slots inthe flanges of said channel member, and means for forcing the saidmembers apart.

4. A quoin comprising, two members movable relatively to each other,means for moving the same comprising a rack adapted to receive a key andmeans for holding the key against separation from the rack, said meansbeing located in the same plane as the said rack.

5. A combination of elements as per claim 4 in which said means alsoprevents movement of the key toward said rack.

6. In combination, a channel shaped member, an outside wedge memberadapted for lateral movement between the ilanges of the channel, aninside wedge having teeth thereon, adapted for longitudinal movementbetween the outside wedge and the web of the channel, a cylindricalshell extending through and between the langes of the channel adapted toreceive a key, said shell being cut away to allow for longitudinalmovement 4of theV teeth on the inside wedge, whereby rotation of saidkey moves the inside Wedge to force the outside wedge away from thechannel, and said inside wedge abutting the cylindrical shell to limitthe movement thereof.

'7. In combination, a channel shaped member, an outside Wedge memberslidable between the flanges thereof, an inside Wedge member havingteeth thereon, the anges `of said channel each having an openingtherein, a cylindrical shell inserted and secured into said openings,one end 0f said shell being shaped to receive a key therein and theother end of said shell being shaped so that a key cannot be insertedtherein, said shell being cut away for the purpose described.
